Can one of you EE chads please help me out.
I'm teaching myself electronics through an EE textbook - these formulas for AC power are confusing me.
I get that RMS needs to be used for P=V^2/R because it's gonna be the mean of all the V^2 values. But why the fuck are RMS values used for P = VI? There are no squares? Why would you use a mean of the squares when neither of the values are squared? Shouldn't it just be the mean of the normal (unsquared) voltage and current?
